Using the equilibrium data shown below for benzene-toluene system at 1 atm with relative volatility of 2.5: a. Construct an enthalpy-composition (H-x-y) diagram for the mixture. b. From the plot, calculate the energy required for 50% vaporization of a 30 mol% liquid solution of benzene in toluene at saturation temperature. c. If the vapor in equilibrium with the liquid phase is condensed, what is the heat load on the condenser in kJ/kg of the solution if the condensate is saturated?
